JOHN M. KELLEY, OF ROCHESTER, NEW YORK.

CARBUR-ETER.

To all whom it may concern:

Be it known that 1, JOHN M. KELLEY, a resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Carbureters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

The invention relates to carbureters suitable for use in gas machines and the like, and has for its object to provide a simple carbureter especially adapted to give a uniform product, and that without the precipitation of moisture, or the accumulation of a residue such as known in the art as bottoms.

The invention consists in the construction hereinafter described and particularly pointed out.

In the accompanying drawings which illustrate the invention and form part of the specification,Figure 1 is a plan view of the carbureter with parts broken away; Fig. 2 is a partial section on line 22 of Fig. 1; Fig. 3 is a partial section through a portion of the casing and two trays; Fig. 3 is a similar View showing a modification. Fig. & is a partial vertical section through the distributing box. Fig. 5 is a side view showing the carbureter supporting an air pump and a tank, and showing pipe connections.

The carbureter comprises a body or casing 1, preferably of sheet metal lined with wood 2, and rectangular. WVithin the lined casing are a plurality of horizontal trays 3, each resting directly upon the one below it. In practice as many as ten or twelve of these trays have been used together. These trays have upturned edges, and against the inside thereof are arranged strips of wood 1 tacked to the wood lining, the tacks extending through holes in the tray edges and tightly clamping the edges.

Lying loosely in each tray and nearly filling it is a cellular structure with longitudinal air passages, large in number and in extent of exposed surface. This device is preferably constructed as follows: Sheets or strips 5 of burlap, or other suitable absorbent material, are laid on opposite sides of a series of strips of wood 6, 6, 6", and may be tacked thereto, as indicated in Fig. 3. The strips or separators are notched along one edge, as

indicated at 6 in Fig. 4, to leave places where the burlap will not be tightly clamped. These places will allow gasolene introduced at any part of the zig zag passage of a tray to flow or creep along the fabric, and become distributed throughout the whole. Midway between successive wood strips the opposite sheets of burlap are united longitudinally, preferably by sewing a seam 7 between each pair of said strips. Such seams tighten the sheets, and subdivide the spaces between the wood strips and between the burlap sheets into plural series of passages. As shown in Figs. 2 and 3, there are four passages, 8, formed between each pair of strips, one of them being completed by the tray next above, or by the cover 9. The edges of the burlap may be sewed together as at 10, but this is not essential.

As shown in Fig. 1, the burlap does not extend quite to either end of the casing, but some of the separators 6 extend to one end, and some, separators 6, to the opposite end, while some separators (3, come short of both ends. Generally the long and short strips alternate, and the long ones extend alternately at opposite ends. Asheet 11 of burlap or the like may be laid on the bottom of (Each tray to give increased carbureting surace.

12 denotes an air inlet pipe or passage which communicates with a pipe 13 from an air pump 14:, which also communicates with the air storage tank 15 at 16.

17 is a cylinder and piston adapted to operate the air pump at intervals substantially as described in my Patent No. 780,355.

In the top tray diagonally opposite the air inlet is a hole 18 communicating with the tray next below, and so on for other trays, the several trays thus having air inlets 18 alternately at opposite corners. There is no raised rim around openings 18, 18 on the upper side with the result that if from any cause more gasolene is introduced in any tray than will be immediately taken up by the fabric therein it will not be held in the tray but will at once flow to a lower level. The carbureter can thus be kept throughout with none of the fabric standing in a body of gasolene, and as hereinafter stated, all the gasolene introduced will be absorbed, and that preferably without fully saturating the fabric. The outlet pipe for the carbureted air is denoted by 79.

Directly under the cover at one end of the carbureter is fixed a distributing box 20 for gasolene, or similar material, and from said box a pipe 21 leads to each of the several trays, as shown in Fig. 4. The pipes 21 extend into passages 8 of the carbureters preferably about half their length, the pipe for the top carbureter being thus indicated in Fig. 1. The exact location of the passage in each tray into which such pipe extends is not essential. Oil-pipes 22 lead from a distant underground tank 23 to an oil pump 24. An oil return pipe from the bottom of the carbureter is denoted by 25.

In use the carbureter may support the air tank, air pump, etc., and the slats 6, 6, 6 being arranged in line vertically, that is, the strips in each tray being directly above those in the lower trays, will give support to the cover or top at different parts intermediate its edges, enabling it to support heavy weights, and also to be thinner than would otherwise be practicable. If desired the wood lining 2 may be divided on planes corresponding to the bottoms of the trays or partitions, as at 2", Fig. 3*, whereby the trays can be separately removed.

Operation: The air pump operating at intervals forces air into tank 15. Air entering inlet 12 passes along a group or series of passages 8 to the opposite end of the casing, where its direction is reversed and passes through another group or series of passages 8, thus following a zig zag path until the outlet port 18 is reached, and such zig zag course is followed through succeeding trays to the outlet 19. At the same time the pump 24, operated by the air pump, draws a small quantity of gasolene (say an ounce and a half) from tank 23 and injects it into box 20, where it divides between the pipes 21 leading to passages 8 in the several trays, where it falls in small quantities onto the absorbent material of the passages into which it flows, and the current of air takes up the volatile vapor in small quantities, at successive points, that is, in the subdivided passages of successive trays. Although pipes 21 are shown leading to but one passage 8 in each of the several trays, this is not an essential feature. But it is found that in this way the gasolene becomes sufficiently distributed by creeping along the sheets 5 and 11, when the latter is used, or along sheets 5 when sheets 11 are omitted, as in Fig. 3". The notches 6 provide places where the sheets 5 will not be tightly clamped, and where the gasolene can there fore readily pass. The air is carbureted in numerous comparatively small channels the walls of which are nearly dry and give off only a minimum amount of vapor from any unit of surface, thereby reducing and practically avoiding such falling in temperature as to cause objectionable formation of frost and deposit of dew. l/Vhen outlet 19 is closed and no carbureted air is being used the machine stops, and un-used gasolene in the carbureter condenses and flows back to its tank 23. It will be seen that the air or carbureted air never passes through the fabric 5 or 11 but only flows along in contact therewith. The exposed parts of the surfaces of the wood are also absorbent surfaces for the gasolene. The gasolene being introduced in such small quantities, as described, the fabric and wood walls of the carbureting passages will not be submerged, or even partially submerged, but will only be dampened thereby.

Having thus described the invention what I claim is,

1. In a carbureter, the combination with a casing, of superposed trays therein, cellular structures complete in themselves and resting removably in the trays, each structure comprising longitudinal passages in groups, the passages of one group being connected to those of the next group successively to form a zig zag course in each tray, the zigzag grouped passages of one tray being connected to like zig-zag passages in the next tray, means for circulating air through the connected passages, and means for introducing gasolene in small quantities to separate passages in different trays whereby the walls of passages of the structures become dampened with gasolene by its spreading along the material thereof.

2. In a carbureter, the combination with a casing, of a cellular structure therein having longitudinal passages, such structure comprising spaced woodstrip separators and layers of absorbent material on opposite sides of the separators, said layers being connected longitudinally between separators whereby several passages are formed between each pair of separators, separator strips being extended alternately at opposite ends to form partitions to direct air back and forth, and air and gasolene inlets and outlets.

3. In a device of the character described, the combination of a tray or support, a series of spaced strips therein shorter than the tray, opposite sheets of burlap or the like on such strips, means connecting the sheets between strips, thereby subdividing the passages, some of said strips being extended to the inclosing tray at one end and others at the opposite end alternately whereby a long subdivided zig zag course is formed, as described.

4. The combination with a carbureter casing including a top or cover, of trays in the casing, cellular structures one for each tray, each complete in itself and resting removably in its tray, said structures comprising spaced wood-strip-separators and absorbent sheet material on opposite sides of the separators, the separators of successive structures being in line vertically from top to bottom of the casing and serving as additional supports for the cover beside supporting and separating the sheets.

5. In a carbureter, the combination of a metal casing, a lining of wood, sheet metal trays having upturned edges, means comprising strips of wood on the inside of the trays for clamping the edges of the trays to the lining, and structures forming connected air passages in the trays.

6. The combination with a casing and trays or supports at different levels therein, of air circulating and carbureting structures therein comprising groups of passages connected to form zig zag subdivided passages in each of the several trays, and means for introducing gasolene or the like directly to passages in such different levels.

7 In a carbureter, the combination of a casing, trays, connected subdivided or grouped air passages in the trays in diflerent planes, a gasolene-distributing box in the top of the casing, and pipes leading from such box directly to air passages in difiierent planes.

8. In a carbureter, the combination with a casing, of carbureting structures in difierent planes therein and having zig zag subdivided air passages connected from one plane to another, said structures being formed of sheets of absorbent material on opposite sides of spaced wood-strip-separators, and means for introducing gasolene or the like in small quantities near the middle of each of a plurality of said structures whereby the walls of the rest of the passages will be merely moistened by gasolene creeping along the absorbent material.

9. In a device of the character described, the combination of a tray or support, a series of spaced and notched separators, 0pposite sheets of absorbent material thereon forming passages between the separators, means for introducing air, and means for introducing gasolene at a selected part in quantities to moisten without over-saturating said absorbent material.

10. In a carbureter, the combination with a casing having a suitable top or cover, of a plurality of air-passage-structures therein, one above another, said structures each comprising spaced and notched separators, layers of fabric on opposite sides of the separators forming passages between the same, said separators of the several structures being arranged in vertical rows from top to bottom of said casing, thereby forming supports for said top, means for introducing gasolene to some of said passages, said notches permitting easy passage of gasolene transversely by the separators.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
